# seep
|
|
|
|
Print `stdin` to terminal, then pipe into next process.
|
|
|
|
`seep` (short for see pipe) has the purpose of letting you peek at what you're
|
|
piping.
|
|
|
|
## Usage
|
|
|
|
On Unix like systems, you can pass the output (`stdout`) of one process to the
|
|
other as input, like this: `echo "foo" | hexdump`. In some cases, the output of
|
|
the first command might contain information that a user might want to look at.
|
|
|
|
When the second process does not show the information it received, the user
|
|
cannot *see* the information produced by the first program. This is where `seep`
|
|
comes useful:
|
|
|
|
To look at the output of process one, we pipe it to `seep` and then pipe the
|
|
output of `seep` to process two. `seep` will show us what information it
|
|
receives and pass it over to process two:
|
|
|
|
```bash
|
|
ls | seep | grep src
|
|
```
|
|
(list files and dirs, show all with `seep`, show only containing "src")
